$19.99 x 4 = $79.96
$22.50 x 6 = $135
$19.99 x 6 = $119.94
$22.50 x 4 = $90
The best answer to this choice is 4 dvds for $19.99. why?, because if it was 6 or 4 dvds for $19.99 the price would be more inexpensive then the price for $22.50, because if it was 22.50 x 4 or 6 dvds the price would be more expensive.
A pound is a unit of weight, not volume.
Good luck!

<span>a.
The radius of earth is about 6400 kilometers. Find the circumference of
a great circle.
Circumference = 2π(radius) = 2π(6400 km) = 40.212,39 km
b. Write an equation for the circumference of any
latitude circle with angle theta
As stated, </span><span><span>the
length of any parallel of latitude (this is the circumference of corresponding circle) is equal to the circumference of a
great circle of Earth times the cosine of the latitude angle</span>:
=> Circumference = 2π*radius* cos(Θ) = 2 π*6400km*cos(Θ) = 40,212.39 cos(Θ)
Answer: circumference = 40,212.39 cos(Θ) km
c. Which latitude circle has a
circumference of about 3593 kilometers?
Make </span><span><span>40,212.39 cos(Θ)</span> km = 3593 km
=> cos(Θ) = 3593 / 40,212.39 = 0.08935 => Θ = arccos(0.08935) = 84.5° = 1.48 rad
Answer: 1.48
d. What is the circumference of
the Equator?
</span>
For the Equator Θ = 0°
=> circumference = 40,213.49cos(0°) km = 40,212.49 km
Answer: 40,212.49 km
8 times 8 is the closest you can get to 71 without going over, since 8 times 9 would be 72.
